Programs for preparing a 3D model for printing on a printer

3D printing technology has improved significantly over the past decade. And now it is taking more and more sectors of the economy by storm. So far, it has been successfully used in various fields, ranging from medicine and manufacturing to socio-cultural sectors.

However, 3D modeling is not easy to master. Sometimes it becomes frustrating to work with 3D modeling tools, and if you are a beginner, designing and printing a simple structure can take days or even weeks.

Below, you'll find easy-to-use 3D printing tools that feature innovative designs, extraordinary capabilities, and seamless integration with your computer hardware. We have provided all the information about the qualification level and where you can download them.

Sculptris

Price: Free Platform: Windows / macOS

Sculptris is a virtual sculpting tool that mainly focuses on the concept of clay sculpting. This would be a great choice if your project revolves around creating statues or characters from comics and video games.

Even though the tool is designed for beginners, it still contains many incredible features that make 3D sculpting very easy. For example, in Sculpt mode you can edit mesh geometry with simple brush strokes. In paint mode, you can easily paint textures (with brushes) wrapped onto the surface of the mesh.

Sculptris regularly analyzes the model's surface to ensure details are projected correctly and automatically adds polygons when necessary.

Overall, it provides an impressive gateway to the world of 3D. You can create basic models and then enhance them in other advanced programs such as ZBrush. In fact, Sculptris is made compatible with ZBrush, so users can import their work into advanced 3D tools when they're ready to take their designs to the next level.

Wings 3D

Price: Free Platform: Windows / macOS / Linux

Wings 3D is an open source program that uses an internal data structure to store coordinates and adjacency data. There are four different selection modes for changing the model's geometry: Edge, Vertex, Face and Body. Each has its own set of mesh tools that offer both basic and advanced functionality.

Standard tools (such as move, scale, rotate, bevel, bridge, cut and weld), virtual mirror (for symmetrical modeling) and smooth preview make it easy to create a 3D model.

Although it doesn't support animation, you can use it to create mid-range polygon models and add textures and materials using AutoUV renderers and OpenGL renderers. You can then export the file to external rendering programs such as YafRay and POV-Ray.

Programs for 3D printer

In recent years, 3D printing has become increasingly popular and accessible to ordinary users. Prices for devices and materials are becoming cheaper, and a lot of useful software is appearing on the Internet that allows you to perform 3D printing. Representatives of software of this kind will be discussed in our article. We have selected a list of multifunctional programs designed to help the user set up all 3D printing processes.

Repetier-Host

First on our list is Repetier-Host. It is equipped with all the necessary tools and functions so that the user can carry out all the preparation processes and the printing itself, using only it. The main window contains several important tabs in which the model is loaded, printer parameters are set, slicing is started, and printing is started.

Repetier-Host allows you to control the printer directly during processing using virtual buttons. In addition, it is important to note that cutting in this program can be carried out by one of three built-in algorithms. Each of them builds its own unique instructions. After cutting, you will receive a G-code, available for editing, if suddenly some parameters were set incorrectly or the generation itself was not entirely correct.

CraftWare

The main task of CraftWare is to perform cutting of the loaded model. After launch, you are immediately transferred to a convenient working environment with a three-dimensional area where all manipulations with the models are carried out. The representative in question does not have a large number of settings that would be useful when using certain printer models; there are only the most basic cutting parameters.

One of the features of CraftWare is the ability to monitor the printing process and configure supports, which is done through the corresponding window. The disadvantages are the lack of a device setup wizard and the inability to select printer firmware. The advantages include a convenient, intuitive interface and built-in support mode.

3D Slash

As is known, printing of three-dimensional models is carried out using a ready-made object, previously created in special software. CraftWare is one such simple 3D model creation program. It is suitable only for beginners in this business, since it was developed specifically for them. It does not have heavy functions or tools that would allow you to create a complex realistic model.

All actions here are performed by changing the appearance of the original figure, such as a cube. It consists of many parts. By removing or adding elements, the user creates his own object. At the end of the creative process, all that remains is to save the finished model in a suitable format and move on to the next stages of preparation for 3D printing.

Slic3r

If you are new to 3D printing and have never worked with special software, then Slic3r will be one of the best options for you. It allows you to prepare the figure for cutting by setting the necessary parameters through the settings wizard, after which it will be automatically completed. It is the settings wizard and almost automated operation that make this software so easy to use.

You can configure the parameters of the table, nozzle, plastic filament, printing and printer firmware. After completing the configuration, all that remains is to load the model and start the conversion process. Upon completion, you can export the code to any location on your computer and use it in other programs.

KISSlicer

Another representative on our list of software for 3D printers is KISSlicer, which allows you to quickly cut the selected shape. Like the program above, there is a built-in settings wizard. Different windows display printer, media, print style, and support options. Each configuration can be saved as a separate profile, so you don’t have to enter everything manually next time.

In addition to the standard settings, KISSlicer allows each user to configure additional slicing parameters, which include many useful details. The conversion process does not last long, and after it all that remains is to save the G-code and start printing using different software. KISSlicer is distributed for a fee, but a trial version is available for download on the official website.

Cura

Cura provides users with a unique algorithm for creating G-code for free, and all actions are performed within the shell of this program. Here you can configure the parameters of devices and materials, add an unlimited number of objects to one project and perform the cutting itself.

Cura has a large number of supported plugins that you just need to install and start working with them. These extensions allow you to change G-code settings, customize printing in more detail, and apply additional printer configurations.

3D printing is not complete without the use of software. In our article, we tried to select for you some of the best representatives of such software, used at different stages of preparing a model for printing.

We are glad that we were able to help you solve the problem. Add the Lumpics.ru website to your bookmarks and we will be useful to you. Thank the author and share the article on social networks.

Method 3: SketchUp

Many users know SketchUp as a tool for modeling houses, but the functionality of the software is much broader, so it can be used as a tool for working with models in preparation for 3D printing. SketchUp is on our list today because it is easy to import ready-made free models for editing and further saving in the desired format. Let's look at all aspects of managing this software one by one.

Step 1: First launch and working with models

First, we suggest that you familiarize yourself with the basic principle of interaction with SketchUp in order to understand exactly how to add and manage models. Next, we will leave a link to training materials if you want to study this solution in more detail.

1. After installing and launching SketchUp, you need to click on the “Login” button to connect your user account. If you have started the trial period, then from this moment the countdown of days begins until it ends.
2. When the "Welcome to SketchUp" window appears, click on "Simple" to go to the workspace.
3. Drawing figures in this program is carried out in exactly the same way as in other similar solutions. Hover over the “Draw” section and select a custom shape.
4. After that, it is placed on the workspace and its size is edited at the same time.
5. The remaining buttons on the top panels perform modifier options and are responsible for performing other actions.

As we said before, the SketchUp developers provide a wide variety of training materials on how to interact with this application, not only in text format, but also as videos on YouTube. You can get acquainted with all this on the official website using the link below.

Go to SketchUp documentation

Step 2: Loading the finished model

Not all users want to independently create models that will be sent to print in the future. In such cases, you can download a ready-made project, edit it, and only then export it in a suitable format. To do this, use the official resource from the SketchUp developers.

Go to download models for SketchUp

1. Use the link above to go to the main page of the site to search for models. There, confirm the license agreement to start using it.
2. Next, we suggest using the built-in category search function to quickly find a suitable model.
3. Find an option in the list, and also pay attention to additional filters.
4. After selecting the model, all that remains is to click on “Download”.
5. Run the resulting file through SketchUp.
6. Review the model and edit it if necessary.

Step 3: Export the finished project

Finally, all that remains is to export the finished project for further printing on your existing device. You already know in what format you need to save the file, and this is done like this:

1. Hover over the "File" - "Export" section and select "3D Model".
2. In the Explorer window that appears, you are interested in the OBJ or STL format.
3. After choosing the location and format, all that remains is to click on “Export”.
4. The export operation will begin, the status of which you can monitor yourself.
5. You will be informed of the results of the procedure and can proceed with the printing task.

You just learned about three different 3D modeling programs that are suitable for creating any job yourself for printing on a 3D printer. There are other similar solutions that allow you to save files in STL or OBJ format. We recommend that you familiarize yourself with their list in situations where the solutions described above do not suit you for some reason.

Method 2: Autodesk Fusion 360

The following program, called Autodesk Fusion 360, is available for free private use for a year, so it is quite suitable for mastering and creating simple models in order to print them in the future on existing equipment. We decided to make the introduction to this software the same as with Blender, so we created a step-by-step division.

Step 1: Preparatory Steps

In Autodesk Fusion 360, you don't have to manually activate toolbars or select any unusual options. The user just needs to make sure that the project metrics are correct and, if necessary, change the properties of the view sides, which happens like this:

1. After downloading and installing Autodesk Fusion 360 from the official website, the first launch should occur. No initial windows will be displayed, so a new project will be created automatically. Pay attention to the “Browser” section, which is located on the left under the main panels. Here, select "Document Settings" to expand this section.
2. Proceed to edit the “Units” file if the standard value in millimeters does not suit you.
3. In the block displayed on the right, select the optimal unit of measurement, which you will have to follow throughout the entire time you interact with the project.
4. After that, check out the “Named Views” and “Origin” sections. Here you can rename each side to suit your personal preferences and customize the display of the axes in the workspace.
5. To complete the configuration, make sure that the “Design” space is selected, because this is where the initial creation of all objects occurs.

Step 2: Designing a Model for Printing

If you are faced with the need to manually develop a model using Autodesk Fusion 360, you will have to study this program for a long time, or at least familiarize yourself with the basics. Let's first take a look at a simple example of adding shapes and editing their size.

1. Open the Create list and see the available shapes and objects. As you can see, all the main figures are present here. Just click on one of them to proceed to adding.
2. Additionally, take a look at the other elements on the top panel. The main space here is occupied by modifiers. The design of their icons makes it clear what they are responsible for. For example, the first modifier extrudes the sides, the second rounds them, and the third creates an indentation.
3. After adding object shapes to the workspace, levers will appear, by moving which you can adjust the size of each side.
4. When making adjustments, also look at the separate field with dimensions. You can edit it yourself by setting the required values.

We have already talked about the main features that must be followed when reviewing Blender, so we will not dwell on this again. Instead, we suggest learning the rest of the interaction with Autodesk Fusion 360 by reading the official documentation on the site in order to master the creation of not only primitives, but also objects of a much higher level of complexity.

Go to Autodesk Fusion 360 documentation

Step 3: Prepare to Print/Save Document

As part of this stage, we will talk about two different actions that are directly related to 3D printing. The first is to submit the job immediately through the software you are using. This option is suitable only in situations where the printer itself can be connected to a computer and communicates with such software.

1. In the “File” menu, activate the “3D Print” item.
2. A block with settings will appear on the right. Here you only need to select the output device itself, if necessary, enable preview and start the task.

However, now most standard printing devices still only support flash drives or operate exclusively through proprietary software, so the need to save an object arises much more often. This is done like this:

1. In the same “File” pop-up menu, click on the “Export” button.
2. Expand the "Type" list.
3. Select “OBJ Files (*obj)” or “STL Files (*.stl)”.
4. After that, set the save location and click on the blue “Export” button.
5. Wait for the save to finish. This process will take literally a few minutes.

If such an export fails, you will need to save the project again. To do this, click on the special button or use the standard key combination Ctrl + S.

MeshLab

Price: free Platform: Windows | macOS | Linux

MeshLab is an open source program for editing and processing 3D triangular meshes. It contains many functions for checking, editing, texturing, rendering and transforming meshes.

With the visualization feature, you can graphically visualize the smallest details of a 3D model, control camera perspective, and use built-in canonical views. Move different grids into a common frame of reference, reconstruct the shape of any object, and easily control its scale, position, and orientation.

There are a variety of Photoshop-style filters for adjusting vertex and edge colors, such as brightness, contrast levels, gamma, saturation, sharpening, and smoothing. There are also additional filters for calculating volumetric occlusion and external occlusion and matching them to the color of vertices and edges.

MeshLab work can be exchanged with other popular third-party tools, including SketchFab, Autodesk, and Blender. This makes it easy to expand your project and work with multiple 3D programs.

MeshLab has been used for rapid prototyping in orthopedic surgery, benchtop manufacturing, and in many academic and research contexts such as surface reconstruction, cultural heritage, and microbiology.

3D printer software

The selection of software is carried out based on the available equipment. If a 3D scanner is available, specially developed modeling and equipment control programs are used. If you have Kinect, both paid and free software will do.

If you don’t have a scanner or Kinect, a camera will do, but in this case you’ll need programs from the Autodesk 123D Catch series. With their help, it is possible to both simulate structures and control equipment. Attention should be paid to the possibility of using the Russian language. You can download the software for free.

All software for creating three-dimensional objects are divided into three groups. The first includes those programs with the help of which modeling takes place.

Among them:

• Autodesk 3Ds Max

You can use it to depict anything. Mastering the program is not easy, but there are enough ways to do it. A beginner has free classes in the virtual space and community at his disposal. It is necessary to note that the license is in the public domain. When using it, you need to take into account that all models will be hollow. If there are holes, Autodesk 3Ds Max will not create the required 3D design when printing;

Autodesk 3ds Max software

• SolidWorks

The program is designed for high-precision modeling, therefore, working with it will require knowledge in the field of drawing and geometry. As a result of its application, filled objects will appear;

• Thinkcard

The program for creating a model on a 3D printer is distinguished by its cartoonish stylization, since it was created for the children's community, and the presence of a selection of ready-made 3D objects.

The second includes the software that powers the 3D printer. Preparing a 3D structure before printing is an important stage in creating a three-dimensional model:

1. AutoDesk 3D Print Utility. This optional program can be downloaded for free. It is capable of correcting errors made during modeling and checking through calculations and visualization of the material.
2. This is software characterized by a wide range of plugins and settings. It should also be noted that there is a high-speed slicer and the ability to download it for free. This universal control program allows you to change the temperature regime. Today Cura is the highest quality software.
3. The software is developed for MakerBot brand 3D printers. Its advantages are a simple and convenient interface, as well as compatibility with similar equipment.
4. Repetier host. 3D printer program in Russian for professionals. It is not recommended for beginners to work with it. It has many features and the ability to use third-party slicers.

The last step is to select software, the purpose of which will be to print the simulated and prepared object. The 3D printer control program Cura 15.02.1 is considered one of the most advanced. The Type 3 control program is also common, mainly due to the fact that work with this software is carried out in Russian.

MatterControl

Price: free Platform: Windows | macOS | Linux

MatterControl is a comprehensive software package that lets you design, slice and manage 3D prints. You can browse existing designs (by visiting Design Apps) or create objects from scratch using Design Tools.

If you have a dual extrusion 3D printer, the software makes it easy to select which extruder will print specific parts. Once the model is imported or created, you have the ability to remove or replace parts, align them to their origin, and tell the printer which extruder to use for certain areas of the design.

SolidWorks

Price: Available on request. Platform: Windows

SolidWorks is computer-aided engineering (CAE) and computer-aided design (CAD) software for Microsoft Windows. It is used by millions of designers and engineers in more than 100,000 companies.

Written in the Parasolid kernel, the software uses the parametric functional method to develop models and assemblies. It is quite easy to get to know and comes with a lot of functionality.

Although 3D sketches are available for professional users, most people start with a 2D sketch. A sketch contains geometry in the form of points, arcs, lines, conics, and splines. You can add dimensions (to define the location and size of the geometry) and relationships (to define attributes such as perpendicularity, parallelism, tangency, and concentricity).

The software automatically generates views from the solid model. You can easily add notes, dimensions, and tolerances to your drawing at any time. Your work is saved in the Microsoft Structured Storage file format, so you can open and edit it on other platforms from other providers.

Fusion 360

Price: 30-day free trial | $495 per year Platform: Windows / macOS

Fusion 360 is a cloud-based 3D CAD software developed by Autodesk. It handles the entire process of designing, testing and executing a 3D structure.

CATIA is probably the best 3D printing software for professional users. This means an automated 3D interactive application.

Developed in 1977 by the French company Dassault Systemes, CATIA provides a unique capability for modeling complex products. Over the years, it has evolved into more than a CAD software package: it is now a software package that includes computer-aided design and manufacturing capabilities.

The software has a fully loaded library with all the materials needed to develop projects at different scales. Unlike other 3D modeling tools of its kind, which require a powerful PC, CATIA can run on low-cost desktops and laptops.

It is used in many industries, including automotive, aerospace, defense, life sciences, consumer products and industrial equipment.

Review of 3D modeling and printing programs on a 3D printer.

Many 3D printer users sooner or later have a problem with the availability of virtual models for printing. Of course, simple 3D models, for example: a phone case, toys, chess pieces and home accessories can be downloaded from specialized websites. But it is not always possible to find the right one, and then you have to master special programs for 3D modeling.

Thanks to the 3D printing revolution and the availability of 3D printers, there are now many different programs and applications for creating 3D models. Gone are the days when special education, knowledge of technical English and a lot of time were required to create the simplest virtual, three-dimensional 3D model. There are many large professional modeling programs that specialists use to create 3D graphics and complex multi-layer virtual models. All of them are quite expensive, require a lot of time to study, and are demanding on the system capabilities of the computer and its components.

In our article, we decided to describe the most popular and prominent free and shareware programs and web applications for 3D modeling, which are ideal for home use. The programs can be used on inexpensive computers, some can be installed on a tablet or smartphone.

Cura

Price: free Platform: Windows | macOS | Linux

Cura is an open source application for slicing 3D printers. It is available under the LGPLv3 license, so you can integrate it with third-party CAD applications.

Like other 3D printing software, it splits the model file into multiple layers and generates printer-specific g-code. Its super clean interface and minimalist layout allows you to add any additional features or options you might need. You can then send this G-code to a printer to print the physical object.

Cura is compatible with almost all desktop 3D printers and supports common 3D formats including OBJ, STL, 3MF, X3D. It also works with image file formats such as PNG, JPG, GIF and BMP.

Program for 3D printers Cura 15.02.1

Cura is another of the available free G-code generation apps for 3D printers. It can also be used to control a 3D printer via a COM port, but I did not test this feature due to the lack of it in the relatively old BFB Rapman printer that I have, which can only print from a flash drive.

The first thing we see after launching Cura for the first time is the main application screen with basic settings:

The current version has support for the Russian language, which, however, is still partial:

In the Russian version, the main screen looks like this:

In the window on the right you can look at both the 3D view of the model and the generated trajectory in the “many layers” or “single layer” mode:

At the same time, in the “many layers” mode for some reason for code flavor

(
G-code type
) BFB and Mach3/LinuxCNC produces a gap between the blue and green layers.
For other code flavors,
trajectories in this gap are drawn with a smooth transition from yellow to green, which should probably symbolize the cooling of the layers.

Setting up a simple "top view" for program authors is probably too easy, and requires fiddling with the mouse to get roughly what you want. The keyboard can also be used - we use the arrows to rotate, and to move through layers in the path viewing mode, use the up/down arrows while holding down Shift or Control.

For code flavor

BFB and Mach3/LinuxCNC trajectory is shown as blue lines without thickness, including idle transitions,

For other G-code types, the color of the paths is different for outer/inner walls, fill and idle, and the path itself has a thickness:

However, at high magnification, instead of solid lines, we will see a uniform disgrace:

All settings have tooltips, which greatly helps you understand what's what. It’s a little confusing that the print speed is indicated in the basic

, and the remaining speeds are in the
advanced
:

Interesting tab “Extensions”:

The Tweak extension results in the following trajectory:

And in the real process it will look like this:

As a result, the robot will have an “antenna”. It is not clear whether these extensions can be used in real life, but there is no way to disable these applications back except to “clear your profile.”

On the last tab (which does not appear for all types of G-code) you can edit the start and end sections for your printer's G-code, which is taken from the corresponding ini file (see below)

The 3D printer settings look like this:

The most important thing is the type of G-code

(
code flavor
), which is offered to choose from the following options:

What these options are is indicated in the tooltip:

When setting up a new printer (or during the initial installation of the program), a wizard appears:

If you select the last item, then the following options will be offered:

The Custom option leaves very little chance:

But in other cases, printer profiles are located in the \resources\machine_profiles folder:

At first glance, the profiles look like they can be configured to do anything:

Cura allows you to read the following file types:

Availability of gcode

in the list of formats it is very pleasing, but the joy disappears when viewing layer by layer. Some layers are completely gone, some are left with only “horns and legs”, idle transitions:

Importing images allows you to get a relief image in which the height corresponds to the brightness:

STL files are read relatively quickly and correctly. However, one of the 35 test files, named, as luck would have it, sample

did not boot without producing any diagnostics.

STL processing occurs “on the fly” - after reading the file and whenever parameters are changed. For small files this is not a problem, but, for example, rotating an object like a skull at the desired angle to the horizon must be slow and sad.

Supports are generated automatically, of two types. There is only one option for internal filling: a square grid at an angle of 45 degrees to the axes.

Setting up for a specific BFB printer pleased me with a neatly laid out rake.

Firstly, when selecting the G-code type

BFB in a file with G-code, instead of the “correct” line ends 0x0D 0x0A, the result is 0x0D 0x0D 0x0A:

And the printer controller reacts to this in a very unique way - everything works except for the thread feed, which is set by command M108. You can combat this by reading and writing the file in any text editor, but you still had to think of that.

Secondly, I still don’t understand how and where Cura gets the value for the thread feed speed in this command.

If anyone is not entirely clear what this is: M108 S400 Set Extruder 1 speed to S value/10 = 40rpm

As a result, in order to achieve the “standard speed” of feed, it was necessary to set the fluidity coefficient (Flow%) to an abnormal value of 4250%. In the normal case, this is “the fluidity of the material, the amount of material extruded is multiplied by this coefficient” and usually should not be more than 150. As a result, the length of the fishing line and the weight of the model are calculated incorrectly. If we set the fluidity to 100%, then the weight of the robot in the example is calculated to be 4 grams. Real weighing showed 3.4

Yes, the “antenna” is bent, it looks like I didn’t enable the pause at height

.

Update

: the density of the material is set in the “program settings” (well, it’s logical), and by default the density of PLA is 1240 kg/m3, and for ABS you need to set it to 1040, and then the program will estimate the weight of the robot at 3 grams.

Update 2

: It should be added that Cura does not read “foreign” G-code, and for BFB
type G-code
the filling is not shown in the trajectory viewing mode.

What does Cura show?

What happens in reality (the contrast in the picture is turned up).
